[0023] 5. After the monitor is damaged, the push plate moves upward, and through the cooperation of the elastic component, the lifting block and the metal conductive block, the battery and the alarm form a closed current loop through the first wiring tube, the second wiring tube, the current wiring tube, the third metal joint and the fourth metal joint, so that the alarm sounds an alarm, further improving the security reliability of the device.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Reference Figure 1-Figure 9 A multimedia wireless security device includes a mounting base 1, on which connecting ears 2 are symmetrically fixedly installed, a mounting cavity 3 is opened inside the mounting base 1, and a conical hole 4 with a trapezoidal longitudinal section connected to the mounting cavity 3 is opened at the bottom of the mounting base 1. The installation device can be installed through the two connecting ears 2 on the mounting base 1.

[0036] A circular plate 5 is slidably inserted in the conical hole 4, and a monitor 7 is fixedly installed on the lower surface of the circular plate 5 through a connecting seat 6. The monitor 7 is wirelessly connected to the multimedia display screen of the backstage central control, and the staff can monitor in real time through the multimedia display screen. A push plate 9 is sealed and slidably installed in the installation cavity 3 through multiple reset springs 8. The lower surface of the push plate 9 is connected to the circular plate 5 through multiple groups of hinge components. The hinge components include two connecting blocks 13, two articulated balls 14 and a telescopic rod 15. The two connecting blocks 13 are respectively fixedly installed on the circular plate 5 and the push plate 9. Spherical grooves are opened on the opposite sides of the two connecting blocks 13. The two articulated balls 14 are respectively rolled and embedded in the spherical grooves, and the two ends of the telescopic rod 15 are respectively fixedly connected to the two articulated balls 14.

[0037] The circular plate 5 is slidably inserted in the conical hole 4. When the circular plate 5 moves, the circular plate 5 will move along the inclined surface of the conical hole 4. Under the action of the inclined surface, the circular plate 5 will move a certain distance in the vertical direction. The circular plate 5 is connected to the push plate 9 by two connecting blocks 13, two articulated balls 14 and a telescopic rod 15. When the circular plate 5 moves, the articulated balls 14 will be driven to rotate in the spherical groove, and at the same time, the telescopic rod 15 will be driven to undergo tensile and compressive deformation, thereby ensuring that the circular plate 5 can move in the conical hole 4 when it is connected to the push plate 9.

[0038] Support blocks 10 are symmetrically fixedly installed on the lower surface of the push plate 9, and rectangular holes are provided on the two support blocks 10. Rectangular clamping blocks 11 are slidably installed in the two rectangular holes. Slots 12 are provided on the inner walls of both sides of the installation cavity 3, and one end of the rectangular clamping block 11 is inserted in the slot 12. A transmission component for driving the two rectangular clamping blocks 11 to approach each other is provided in the installation cavity 3.

[0039] The push plate 9 is installed in the installation cavity 3 through multiple return springs 8. One ends of the two rectangular blocks 11 are respectively inserted into the two slots 12. Under the action of the rectangular blocks 11 and the slots 12, the movement of the push plate 9 is restricted. At this time, the multiple return springs 8 are in a compressed state.

[0040] The transmission assembly includes two hinged rods 16 rotatably mounted on one end of the two rectangular blocks 11, a top plate 17 hinged to the two hinged rods 16, and a top rod 18 vertically fixedly mounted on the circular plate 5, the upper end of the top rod 18 contacts the lower surface of the top plate 17.

[0041] The top plate 17 is connected to the two rectangular blocks 11 through two hinged rods 16. The upper end of the top rod 18 contacts the lower surface of the top plate 17. The rectangular block 11 is installed on the lower surface of the push plate 9 through the support block 10. When the monitor 7 is damaged, the circular plate 5 will move in the conical hole 4 under the action of the destructive force, and move an end distance upward in the conical hole 4. At this time, the circular plate 5 will drive the top rod 18 to move upward, and the upper end of the top rod 18 will slide relative to the lower surface of the top plate 17. The top plate 17 is driven to move upward, and the top plate 17 will drive the two rectangular blocks 11 to approach each other through the two hinged rods 16, and one end of the rectangular block 11 is taken out from the slot 12, thereby releasing the lock on the push plate 9. Under the action of the elastic force of the reset spring 8, the push plate 9 will drive the connecting seat 6 and the monitor 7 to move into the installation cavity 3. When the monitor 7 moves upward, it can play a buffering role, which can reduce the damage to the monitor 7 by the destructive force, and ensure that the surveillance video in the monitoring equipment can be extracted later.

[0042] A liquid storage space is formed between the upper surface of the push plate 9 and the inner wall of the mounting cavity 3, and the liquid storage space is filled with fluorescent liquid. A spray assembly for spraying the fluorescent liquid is provided on the mounting seat 1, and the spray assembly includes an annular tube 19 fixedly mounted on the mounting seat 1, a plurality of nozzles 20 all connected to the annular tube 19, and two connecting tubes 21 symmetrically fixedly connected to the annular tube 19. Connecting holes connected to the interior of the mounting cavity 3 are provided on both side surfaces of the mounting seat 1, and one end of the connecting tube 21 is fixedly inserted in the connecting hole.

[0043] Fluorescent liquid is a prior art. When the fluorescent liquid is sprayed on the human body, it cannot be cleaned in a short time and can fluoresce at night. The fluorescent liquid is filled in the liquid storage space formed between the upper surface of the push plate 9 and the inner wall of the installation cavity 3. When the push plate 9 moves upward under the elastic force of the reset spring 8, the fluorescent liquid will be squeezed into the connecting tube 21, and then the fluorescent liquid will enter the annular tube 19 through the connecting tube 21. Finally, the fluorescent liquid is sprayed around through multiple nozzles 20. The sprayed fluorescent liquid can be sprayed on the illegal person at the first time. When the police arrest the illegal person later, they can arrest him according to the marks left by the fluorescent liquid, which provides convenience for the police.

[0044] A monitoring wiring tube 22 is connected to the monitor 7, and one end of the monitoring wiring tube 22 is fixedly connected to a first metal joint 23. A mounting hole communicating with the interior of the mounting cavity 3 is provided on the side of the mounting seat 1. A power wiring tube 24 is fixedly inserted in the mounting hole. One end of the power wiring tube 24 is fixedly connected to a second metal joint 25. The first metal joint 23 contacts the second metal joint 25. The monitoring wiring tube 22 is a tube with wires inside. The wires are protected inside the tube. When the monitoring wiring tube 22 is connected, the wires inside are electrically connected to the monitor 7, and the other end of the wires is connected to the first metal joint 23. The principles of the power wiring tube 24, the first wiring tube 28, the second wiring tube 29 and the current wiring tube 31 in the present invention are all the same. One end of the power wiring tube 24 away from the second metal joint 25 is connected to an external power source. The external power source and the monitor 7 are electrically connected through a connecting wire, which is not shown in the figure. When the first metal joint 23 contacts the second metal joint 25, a closed loop is formed between the external power source and the monitor 7, and the monitor 7 can be used normally at this time.

[0045] When the monitor 7 is damaged, the push plate 9 drives the monitor 7 to move into the installation cavity 3, and at the same time drives the first metal joint 23 and the second metal joint 25 to separate. At this time, the monitor 7 is disconnected from the external power supply, the monitor 7 is powered off, and the operation is stopped to avoid internal circuit short circuit after the monitor 7 is damaged, causing secondary damage.

[0046] An alarm 26 is fixedly mounted on the side of the mounting base 1, and a battery box 27 is fixedly mounted on the lower surface of the mounting base 1. A battery is inserted in the battery box 27. The positive and negative poles of the battery box 27 are respectively fixedly connected with a first wiring tube 28 and a second wiring tube 29. One end of the second wiring tube 29 is electrically connected to the alarm 26. One end of the first wiring tube 28 extends into the mounting cavity 3 and is fixedly connected to a third metal joint 30. The alarm 26 is electrically connected to a current wiring tube 31. One end of the current wiring tube 31 extends into the mounting cavity 3 and is fixedly connected to a fourth metal joint 32. The third metal joint 30 and the fourth metal joint 32 are on the same horizontal plane and do not touch each other. A connecting component for connecting the third metal joint 30 and the fourth metal joint 32 is provided in the mounting cavity 3.

[0047] One end of the first wiring tube 28 for mounting the third metal connector 30 and one end of the current wiring tube 31 for mounting the fourth metal connector 32 are both mounted in the mounting cavity 3 and on the same horizontal plane. When the third metal connector 30 is separated from the fourth metal connector 32, the battery is disconnected from the alarm 26. When the third metal connector 30 and the fourth metal connector 32 are connected via a connecting component, a closed loop can be formed between the battery and the alarm 26 via the battery box 27, the first wiring tube 28, the second wiring tube 29 and the current wiring tube 31. At this time, the battery provides current to the alarm 26, and the alarm 26 sounds an alarm, further improving the security reliability of the device.

[0048] The connecting component includes a lifting block 33 vertically slidably installed in the installation cavity 3 through an elastic component, a metal conductive block 34 fixedly installed on the lifting block 33 and a limit rod 35 fixedly installed on the lower surface of the push plate 9, the lower end of the limit rod 35 contacts the upper surface of the lifting block 33, the elastic component includes a vertical rod 36 vertically fixedly installed in the installation cavity 3, a stopper 37 fixedly installed on the upper end of the vertical rod 36 and a telescopic spring 38 sleeved on the vertical rod 36, and the two ends of the telescopic spring 38 are respectively fixedly connected to the lifting block 33 and the inner wall of the installation cavity 3.

[0049] The lifting block 33 is vertically slidably installed in the installation cavity 3 through the vertical rod 36. The lifting block 33 can only move up and down on the vertical rod 36. The two ends of the metal conductive block 34 are respectively located directly below the third metal joint 30 and the fourth metal joint 32. When the push plate 9 is locked in the installation cavity 3, the lower end of the limit rod 35 installed on the push plate 9 contacts the upper surface of the lifting block 33. Under the action of the limit rod 35, the lifting block 33 is restricted from moving upward. At this time, the telescopic spring 38 is in a compressed state. When the push plate 9 is unlocked, the push plate 9 will drive the limit rod 35 to separate from the lifting block 33. At this time, under the action of the elastic force of the telescopic spring 38, the lifting block 33 will drive the metal conductive block 34 to move upward. When the two ends of the metal conductive block 34 are respectively in contact with the third metal joint 30 and the fourth metal joint 32, a closed circuit will be formed between the battery and the alarm 26, and the alarm 26 will sound an alarm.

[0050] In the present invention, when an illegal person invades and destroys the monitor 7 in the security equipment, the monitor 7 will be subjected to an upward destructive force. Under the action of the destructive force, the circular plate 5 will be driven to move in the conical hole 4, and at the same time, it will move an end distance upward in the conical hole 4. At this time, the circular plate 5 will drive the two rectangular blocks 11 to approach each other through the transmission of the top rod 18, the top plate 17 and the hinged rod 16, and one end of the rectangular block 11 will be taken out from the card slot 12 to release the lock on the push plate 9. At this time, the push plate 9 will be driven by the elastic force of the reset spring 8 to move upward, and at the same time, the connecting seat 6 and the monitor 7 will be driven to move into the installation cavity 3. The direction of movement of the monitor 7 is the same as the direction of the destructive force, so that it can play a buffering role, reduce the damage of the destructive force to the monitor 7, and ensure that the surveillance video in the monitoring equipment can be extracted later.

[0051] When the push plate 9 moves upward, the fluorescent liquid in the installation cavity 3 will be squeezed into the connecting tube 21 and the annular tube 19, and then sprayed out through multiple nozzles 20. The sprayed fluorescent liquid will be sprayed on the illegal persons. When the police arrest illegal persons later, they can arrest them according to the marks left by the fluorescent liquid, which provides convenience for the police.

[0052] When the push plate 9 drives the monitor 7 to move upward, it will also drive the monitoring wiring tube 22 to move upward, thereby separating the first metal joint 23 and the second metal joint 25. When the first metal joint 23 and the second metal joint 25 are separated, the circuit between the monitor 7 and the external power supply is disconnected. At this time, the monitor 7 is in a power-off state and stops operating, so as to avoid internal circuit short circuit after the monitor 7 is damaged, thereby causing secondary damage.

[0053] When the push plate 9 moves upward, it drives the limit rod 35 to move upward, and the limit rod 35 is separated from the lifting block 33. At this time, under the action of the elastic force of the telescopic spring 38, the lifting block 33 will drive the metal conductive block 34 to move upward. When the two ends of the metal conductive block 34 are in contact with the third metal connector 30 and the fourth metal connector 32 respectively, a closed loop will be formed between the battery and the alarm 26. At this time, the alarm 26 will sound an alarm, further improving the security reliability of the device.

[0054] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
